Yes, I had to tune the computer to match. It’s crucial to get the transmission shifting correctly if you change engines.

For anyone looking to boost performance, I went with a larger cooler and upgraded my fluid to synthetic. Huge difference!

23

That’s a solid upgrade! What brand cooler did you use, and was it easy to install?

I went with a B&M cooler. Install was pretty straightforward, just follow the manual and take your time!

Is the 6L80E suitable for heavy towing? I’m worried about reliability under load.

26

It handles towing quite well when properly maintained. Just make sure you use the right towing fluid and the recommended service intervals.

27

Good to know, thanks! I’ve been debating whether to get a transmission cooler as well.

28

Definitely consider a cooler! It can save you from overheating during those long hauls.

Can someone share their experiences with modifications? I need a little more power for my off-road adventures!

I’ve added a shift kit to mine, and it’s made a world of difference in responsiveness, especially on rough terrain.

Interesting! Did it really enhance the overall driving experience? I’m tempted to try it myself.

Absolutely! The shift kit made it feel more like a manual without losing the convenience of auto. Totally worth it.

If my 6L80E could talk, it would be like, ‘I can take it!’ :joy: I love my setup, but I wonder how it would handle a supercharger.

With a supercharger, you’d just need to keep an eye on the torque management settings. It should be fine if done right!

I pondered over using a 6L80E in my classic car build, but I wonder about the installation fitment…anyone tried?

36

I’ve had my 6L80E for three years now, and regular maintenance has been crucial. I recommend changing the fluid and filter every 30,000 miles to keep it running smoothly.

37

That’s solid advice! I do mine every 25,000, just to be safe. The transmission service kit isn’t too pricey either.

I’ve found that labor costs for repairs can vary widely. Expect about $150 to $300 for routine service if you take it to a shop, which isn’t too bad.

39

That’s reasonable! But I’d love to hear from anyone who did it themselves—any tips?

I tackled the fluid change myself last month. Pretty straightforward with the right tools! Just make sure you have a good pan to catch the old fluid.
